To all whom t may concern.'

Be it known that I, GEORGE L. "RICE, a

citizen of the United States, residing at Chicago, in the county of Cookand State o'f Illinois, have invented certain new and.

useful Improvements in Machines and Methods for vMak/ing CombinationPaper-Fiber Twine, o'f which the following is a full, clear, and exactspecification. .l

This application is a division of application Serial No. 200,896, filedNovember 8, 1917, and the inventionforming the subject matter Ot thisapplication relates to ma'- chines and methods for making combination.paper-fiber twine. y

I am well aware lthat therel are many twines of this general type on themarket which are lmade by covering a fiber center with paper, but in allcases the liber center is spun into a yarn previous to covering the samewith the paper. In other words, the spinning of the fiber center and thecombining of the liber with the paper are two separate and distinctoperations. When the spun center and paper are .being put together inthis manner the tension' on each is separately regulated, 'and thenumber of twists in'the fiber center is entirely independent of andusually differs from the number of twists in the paper covering orsheath. The twine made in this manner is defective` since there is nointertwisting or interlocking of theiiber and the paper, and the papercovering is, therefore, easily stripped 'from' the fiber center.Moreover,

the difference in the number 'of twists per unit of length. in the'fibercenter and paperv cover, and the fact that l.the fibencenter,

having previously been twisted into a twine, receives additional twistwhen the paper 'cover is'applied, results a twine which 'isi stiff andkinky, and unsuitable when employed'in such manner that it must be fedthrough guidingeyes or employed in binding and 'knotting machines.

The object of myln'vention is to provide a stron and flexible' 'paperber twine havcient weather proofing and insect proong qualities to meetthe ordinary conditions, and more' `particularly the conditionsencountered in the use of suchtwine 1n harvest1ngmach1nerya nd moreoverto Fig. 2 vshows an enlarged V detail provide a twine which willnotikink and in I feeding the paper and non-twisted fiber,`

means for folding the paper about the ber, preferably in such a mannerthat the paper will entirely cover the ber'and that portions o'f the berwill be disposed in longitudinal creases in the paper which may beformed by the paper feeding and folding means, and means for spinning ortwisting the paper and ber together. p In a more specific form themachine may embody the elements enumerated below', al-

though it should be distinctly understood that it is not essential thatall of these elements be present for the successful operation of themachine.

The machine in its more specific form, then, embodies means forsimultaneously drawing and `feeding untwisted fiber and a ribbon ofpaper, means for slightly condensing the ber into a loose coreV and forforming \the paper into a tube around this core, means for` crushing orcrimping the paper Onto'the loose ber core 'in such a manner that someof the'bers of the loose core are disposed in the longitudinal seamsformed by the crushing means, and means 'for simultaneously twistingtheuntwisted ber and crimped paper together to form the combinationpaper and fiber twine in which the paper covering is interlocked andintertwistedwith the fiber core.

In the accompanying drawings Iv have` f illustrated one embodiment ofmy'invention, Vand in these vdrawings,--

The usual type ofhorizontal flierA spinning machine is employed, andthis machine embodies a supporti-ng frame '10, the usual Hier frame 11,bobbin 12, and capstan pulleys 13. The paper is carried on a reel v14,supported by the main frame, and passes over an idler pulley 15 and amoistening roller 16, which are supported by the supply tank 17 for themolstening liquor. The roller 16 is positively driven by means gf thegearing 18, 1-9 and 20, the gear 20 ein carrigesl a sprocket 22, whichmeshes with the feeding mechanism for the sliver. This feeding mechanismfor the fiber comprises the usual gill bars 23 'and gill pins 24, drivenin the usual manner. By means of this sprocket 22 and the intermediategearing which is supported by the tank 17, I have provided a positivedrive for the moistening roller 16, and in this manner the amount ofmoisture fed to the paper strip 2'5 can be positively controlled. Theliquid Fin the tank 17 may consist simply of water, Ior an emulsion ofwater and oil, preferably animal or mineral oil, with which the papermay be treated to make it weather proof and insect proof. It is,however, not absolutely essential thatV the paper be treated with oilsince the fiber is always treated with oil, and the intertwisting of thefiber and paper forces and squeezes the oil outwardly into the paper.

The feeding and drawing :mechanism vfor the ribbon of paper and thesliver is substantially the/'same asV that shown in lmy Patent, No.1,217,067, granted February 20,

1917, and consists of a large feeding rollerv 26 mounted above two smallfeeding rollers 27 and 28, the rollers 27 and 28 being positively drivenby suitable gearing mechanism. The shaft for the roller 26 is journaledin a box 29, slidable in a supporting bracket 30, pivoted at 31 to afixed part of the frame. I- have provided suitable means by which theroller 26 may be lifted out of. contact with the rollers 27 and 28, andthis means comprises a link 32 suitably pivoted to a handle or lever 33,which in turn is pivoted at 34- to a fixed part' of the frame. iWhen itis desired to obtain access to the feeding rollers the arm 33 is liftedand'sw'ung about the pivot 34 until the stop 35- contacts with a portion36V of the main frame.,r thereby raising the roller 26.

The ribbon 25 of paper after leaving the moisteningroller 16passes'around an idler 3-7 carried by the main frame, and throughmounted on a pintle 21 which also densing .the sliver.

that the flat paper ribbon and the nontwisted sliver are positively andsimultaneously fed through the machine, the rollers 26, 27 and 28 havingthe same drawing action described and claimed in my Patent No. 1,217,067above referred to. By means of this simultaneous feeding the tension onthe paper andthe sliver is maintained uniform, and this is a distinctadvantage in that it avoids any tendency in the completed paper twine tobreak through unequal strains. y After passing through the feedingrollers 26, 27 and 28 the paper ribbon and the loose ber core are passedthrough a former 40, the main body portion o f this former having theshape of a hollow cone. This conical body portion is provided withlaterally projecting lugs 41, having slots 42, which are provided withsuitable securing means for clamping the former to the frame of thespinning machine. On the insideof this conical body there is secured aguide 43 for the non-twisted fiber, this guide consisting of a groovedor concave member, the side walls of which converge vtoward the front ofthe cone for the purpose of cou- From an inspection of Fig. 2 it will beseen that the front end of this member 42 is disposed substantially inaline with the contacting surfacesv of the feed rollers 26. 27 `and 28,so that the sliver is not defiected materially out of the plane in whichit is fed to the former. The paper after it leaves the feedrollers, asis clearly shown in Fig. 2, vis positively fed into the former andcontacts with the upper wall of the conical body portion, and this wallforms the flat ribbon into a tube, as illustrated in Fig. 6. This'tubeis wrappedV around the loose vber core and is crimped into longitudinalfolds or creases 46, and the tube and the core are simultaneously fedforward to aV Crusher 44. and nipper 45, similar to the correspondmgmembers shown in my patent above referred to. By means of the Crusherand nipper the tube is further crimped and fiber nor the paper istwisted separately,

and that substantially no twisting action takes place until the fiberand paper have 45, when the two elements are simultaneously twistedtogether, and in this way a twine is provided in which the two elementsare simultaneously twisted together, thereby forming a twine in whichthe two elements making up the same have the same number of twistsperunit of length. By .means of this simultaneous feeding the tension onthe paper and ber is maintained uniform, and this is a distinctadvantage in that it avoids `any tendency in the completed twineto breakthrough unequalv strains, and also aids vin interlocking the inner bercore and paper covering together. Moreover, `by twisting the twoelementstogether simultaneously, forming a unitary structure, I have alsosucceeded in roducing a. twine,

the elements 4of which w1llI not be separated from each other by.stripping even when the twine is subjected to severe and unusualuse.
